Analysis of Internet of Things Technology Innovation Situation of Global Intelligent Shipyards Based on Patents

With the integration and innovation of Internet of Things (IoT) technology and advanced shipbuilding technology, the competition pattern, cost structure, and industrial supply chain structure of global shipbuilding market undergo the profound changes. It can help Chinese shipbuilding industry shorten the technology gap and give play to the competitive advantages in the global market competition to track and master the IoT technology innovation situation of global intelligent shipyards. The policy formulation ideas of shipbuilding industry in Japan and Republic of Korea are deeply interpreted with the analysis method of Strength, Weakness, Opportunities, Threats (SWOT). The innovation paths of IoT technology of intelligent shipyards in the United States and Republic of Korea are sorted out and analyzed with the patent technology roadmap. The key nodes of IoT technology path of intelligent shipyard in the United States, Republic of Korea, and China are compared to evaluate the gap between China and advanced countries. It is suggested that China should take Shanghai as the source to accelerate the upgrading of research and development level and build the IoT innovation supply chain of domestic intelligent shipyards.
